Mike, hate to disagree with you but stun guns for snake bite is complete BS. Not all snake venom reacts in the body the same way due to be different toxins, but even at that, the stun gun does not work in the way you described. In all actuality, a stun gun is only useful for increasing the patients heart rate, scaring them, making them more nervous, which increases blood flow. Which is exactly the worst thing you can do for snake bite.
First of all not all snake bite from venomous specie is a hot bite (maximum evonomation). There are different levels of envenomation from none at all to maximum.
The Sawyers Extractor is the best treatment. If you can apply the SE within 2-3 minutes you can extract up to 30 percent of the injected venom. At 30 minutes, it's about 3 percent.
Snake bite is something I have studied extensively after becoming a victim of a 'warm' copperhead bite. I have also been bitten numerous times by non-venomous snakes. All of these have been my fault.
Also, my wife is an RN and has treated many serious and non-serious snake bite victims at the hospital she works at.
Although I will get disagreement on this issue, there are no such thing as the quote '2 stepper' snakes in the U.S. Death fom snake bite is extremely rare, and critical stages from hot bites are usually not reached for several hours in healthy victims. Snake bite is nowhere near the threat as anaphylactic shock, heat stroke, and many other wilderness emergencies.
Also, never try to kill or catch a snake that has bitten someone else. This increases the chances for another victim, and in many cases the hospital does not use antivenin so snake identification is not top priority.
Cutting the bite and tourniquets are also wrong. Keeping the victim calm, keeping the bitten limb at or below heart level and try to immobilize the limb. Then proceed with calm evauation to a primary care facility. Time is a factor so don't waste time on BS myths and cures and begin first aid and evacuation immediately. If you can't find your Sawyers Extractor within the first couple of minutes, begin first aid and evacuate. Last, treat all snake bite as possible envenomation.
The hot bite victim will be in pain and swelling will occur but calm actions and reassuring the patient will go a long way in surviving. Especially since their worst nightmare has come true.
Summerland, very, very few scorpion bites are deadly and usually are the equivalent to a hard hornet sting or bullet ant sting. Granted some African specie are killers. Generally scorpions hurt like hell and swells for a while but typically not deadly. With any sting, allergic reaction is usually the deadliest affect.
If I had my choice of a Sawyers Extractor or Bee Sting kit with injectable Epinephrine for the wilderness, I would choose the bee sting kit, since anaphylactic shock cannot be cured with anything but this, and can kill in minutes.
